Documentation Splitter Skill

Purpose

Single responsibility: Split large documentation sites into multiple focused sub-skills with an optional router skill for intelligent navigation. (BP-4)

Grounding Checkpoint (Archetype 1 Mitigation)

Before executing, VERIFY:

[ ] Total page count is known (run estimation first)
[ ] Documentation categories are identifiable
[ ] Target skill size determined (default: 5,000 pages per skill)
[ ] Router strategy selected (category, size, or hybrid)

DO NOT split without understanding documentation structure.

Uncertainty Escalation (Archetype 2 Mitigation)

ASK USER instead of guessing when:

Category boundaries unclear
Optimal skill size uncertain for target use case
Cross-references between sections complicate splitting
Router vs flat structure decision needed

NEVER arbitrarily split - seek user guidance on boundaries.

Context Scope (Archetype 3 Mitigation)

| Context Type | Included | Excluded | |--------------|----------|----------| | RELEVANT | Doc structure, categories, page counts | Actual page content | | PERIPHERAL | Similar large doc examples | Other documentation | | DISTRACTOR | Content quality concerns | Individual page issues |

Size Guidelines

| Documentation Size | Recommendation | Strategy | |-------------------|----------------|----------| | < 5,000 pages | One skill | No splitting | | 5,000 - 10,000 pages | Consider splitting | Category-based | | 10,000 - 30,000 pages | Recommended | Router + Categories | | 30,000+ pages | Strongly recommended | Router + Categories |

Workflow Steps

Step 1: Estimate Documentation Size (Grounding)

# Quick estimation with skill-seekers
skill-seekers estimate configs/large-docs.json

# Output:
# 📊 ESTIMATION RESULTS
# ✅ Pages Discovered: 28,450
# 📈 Estimated Total: 32,000
# ⏱️  Time Elapsed: 2.1 minutes
# 💡 Recommended: Split into 6-7 sub-skills

Step 2: Analyze Category Structure

# Identify natural category boundaries
skill-seekers analyze --config configs/large-docs.json --categories

# Output:
# Categories detected:
# - scripting: 8,200 pages
# - 2d: 5,400 pages
# - 3d: 9,100 pages
# - physics: 4,300 pages
# - networking: 2,800 pages
# - editor: 2,200 pages

Step 3: Choose Split Strategy

| Strategy | Best For | Description | |----------|----------|-------------| | category | Clear topic divisions | Split by documentation sections | | size | Uniform distribution | Split every N pages | | router | User navigation | Hub skill + specialized sub-skills | | hybrid | Complex docs | Categories + size limits per category |

Step 4: Execute Split

Option A: With skill-seekers

# Category-based split
skill-seekers split --config configs/godot.json --strategy category

# Router-based split (recommended for large docs)
skill-seekers split --config configs/godot.json --strategy router

# Size-based split
skill-seekers split --config configs/godot.json --strategy size --pages-per-skill 5000

Option B: Manual split configuration

{
  "name": "godot",
  "max_pages": 40000,
  "split_strategy": "router",
  "split_config": {
    "target_pages_per_skill": 5000,
    "create_router": true,
    "categories": {
      "scripting": {
        "patterns": ["/scripting/", "/gdscript/", "/c_sharp/"],
        "max_pages": 8000
      },
      "2d": {
        "patterns": ["/2d/", "/sprite/", "/tilemap/"],
        "max_pages": 6000
      },
      "3d": {
        "patterns": ["/3d/", "/mesh/", "/spatial/"],
        "max_pages": 10000
      },
      "physics": {
        "patterns": ["/physics/", "/collision/", "/rigidbody/"],
        "max_pages": 5000
      }
    }
  }
}

Step 5: Scrape Sub-Skills

# Scrape all sub-skills in parallel
for config in configs/godot-*.json; do
  skill-seekers scrape --config $config &
done
wait

# Or sequentially with progress
for config in configs/godot-*.json; do
  echo "Processing: $config"
  skill-seekers scrape --config $config
done

Step 6: Generate Router Skill

# Auto-generate router from sub-skills
skill-seekers generate-router configs/godot-*.json

# Creates godot-router skill that intelligently routes queries

Step 7: Validate Split Results

# Check sub-skill sizes
for dir in output/godot-*/; do
  echo "$dir: $(find $dir -name "*.md" | wc -l) files"
done

# Verify router coverage
cat output/godot-router/SKILL.md | grep -A 50 "## Sub-Skills"

Recovery Protocol (Archetype 4 Mitigation)

On error:

PAUSE - Note which sub-skill failed
DIAGNOSE - Check error type:
- Category overlap → Refine URL patterns
- Uneven split → Adjust page limits
- Orphan pages → Add catch-all category
- Router incomplete → Regenerate after all sub-skills done
ADAPT - Modify split configuration
RETRY - Re-split affected category (max 3 attempts)
ESCALATE - Present split preview, ask user for boundary adjustments

Router Skill Structure

The generated router skill:

# Godot Documentation Router

## Purpose
Route queries to the appropriate specialized Godot sub-skill.

## Sub-Skills

| Topic | Skill | Coverage |
|-------|-------|----------|
| GDScript, C#, scripting patterns | godot-scripting | 8,200 pages |
| 2D graphics, sprites, tilemaps | godot-2d | 5,400 pages |
| 3D graphics, meshes, materials | godot-3d | 9,100 pages |
| Physics, collisions, rigid bodies | godot-physics | 4,300 pages |

## Routing Rules

1. **Scripting questions** → godot-scripting
   - Keywords: script, gdscript, c#, function, variable, class

2. **2D graphics questions** → godot-2d
   - Keywords: sprite, 2d, tilemap, animation2d, canvas

3. **3D graphics questions** → godot-3d
   - Keywords: mesh, 3d, spatial, material, shader, camera3d

4. **Physics questions** → godot-physics
   - Keywords: physics, collision, rigidbody, area, raycast

## Usage

Ask your question naturally. This router will direct you to the appropriate specialized skill.

Example:
- "How do I create a player movement script?" → godot-scripting
- "How do I set up tilemap collisions?" → godot-2d
- "How do I apply materials to a mesh?" → godot-3d

Troubleshooting

| Issue | Diagnosis | Solution | |-------|-----------|----------| | Uneven splits | Category size varies | Use hybrid strategy with max_pages | | Orphan pages | URL patterns incomplete | Add catch-all or refine patterns | | Router confusion | Overlapping keywords | Make routing rules more specific | | Too many skills | Over-segmented | Merge related categories |
